What is a better cpu for quad threaded games? (4 core Kaveri vs. 8 core Vishera)

[cbn]

The maximum amount it wins by is 20%.

The FX 6300 is 55% faster than Athlon x4 860K in the BF4 benchmark (stock clocks comparison):

Furthermore the 860K is stronger in single threading (that's where it wins, really).

I'm not seeing much of an advantage at least in these gaming benchmarks (both stock and overclocked).

We are talking a few percent advantage for Athlon x4 860K in only 3 games (stock clocks) and 1 game (overclocked), but then it loses to FX-6300 in some cases by 10's of percent in the other games.
